Potentially inaccurate results in crowdsale participation with indivisible tokens

[dexX7]

CMPTransaction::logicHelper_CrowdsaleParticipation:

if (!isPropertyDivisible(property)) { // <-- the tokens "invested"
    nValue = nValue * 1e8; // <-- 1e8 is floating
}

There is a difference between:

nValue * 100000000

And:

nValue * 1e8

It looks like 1e8 represents a floating point number.

A few examples:

 23058430093 * 100000000 =  2305843009300000000
 23058430093 * 1e8       =  2305843009299999744 // invalid

 46116860184 * 100000000 =  4611686018400000000
 46116860184 * 1e8       =  4611686018300000256 // invalid

184467440735 * 100000000 = 18446744073500000000
184467440735 * 1e8       = 18446744073500000256 // invalid

This issue is related to #247 and might be fixed on one go.
